I have a 55 Belvedere Sport Coupe with the 259 V8. This car is a 3 speed manual W/OD. When I purchased the car it had what I was told was a early 50's Buick 4 BBL carburetor on an aluminum Edelbrock intake. There was a hand made bracket that held the kickdown switch for the OD, and a rod was put on the carburetor linkage to contact the switch. This car is a fairly low mile car that was well taken care of. I want to put the carburetor and OD arrangement back to original. I have a 55 Plymouth Service Manual that shows the original Carter BBD 2 BBL to be a 2260S for OD. The 4 BBL shows to be a Carter 2253S. I see the OD mentioned with a picture on the 2 BBL, but I see nothing on the 4 BBL. Did both 2 BBL and 4 BBL engines have OD? I have the original IBM card from Chrysler Historical, and it indicates the car being a V8, but no further designation as to 2 BBL or 4 BBL as decoded by Chrysler. It is a 259 as the stamped number indicates behind the water pump. Is there any way to know for sure if this was a 2 BBL or 4 BBL originally? I have the OD switch, but am thinking the original carburetor maybe had a different middle or center piece on the carburetor to accommodate the OD linkage and switch. I am looking for both proper carburetors for this arrangement if anyone has these. This car has dual exhaust which anyone could have added, but when I was under the car I noticed that one side has heat shields above the muffler and the other does not. Does anyone have a car with this arrangement that could post pictures of how it looks on the car? I have an original 2 BBL air cleaner, but not a 4 BBL. Any information and carburetors and a 4 BBL air cleaner would be greatly appreciated.
